Thomas Blundell Pocket Watch

Early American Pocket Watches

Thomas Blundell Pocket Watch

This watch is displayed because of its very unusual silver case that has maker's marks "RS" and "Larmour & Co. Balt." It was acquired in 2016 from Alan Treherne, longtime member of the Antiquarian Horological Society who has served in many leadership roles.

William B. Larmour, watchmaker & jeweler, was born circa 1830 in Ireland and worked in Baltimore, Maryland (circa 1858-1864) alone, and then as Lamour & Company (a retail jewelry business). Larmour was located on Light Street in the 1860's, than on Baltimore Street. The firm was succeeded by W.M. Justis in 1874 (Communications with Voss, 2016).
